Pore solution composition of alkali-activated slag/fly ash pastes (2019, result): “As marked with 369 a dashed black line in the graph, a decreasing trend was generally observed between the 370 concentrations of Si and Ca, which is in line with the literature [24, 44].”
A review: The comparison between alkali-activated slag (Si + Ca) and metakaolin (Si + Al) cements (2010, background): “[66,67] studied the pore solution of alkali-activated GGBFS by NaOH combined with thermodynamic calculation, and they found the solubility of Si increasedwith pHwhile that of Ca decreased.”
Hydration and properties of sodium sulfate activated slag (2013, background): “Previous studies by other researchers have also detected CSH as the main reaction product of AAS [28, 40, 43, 44, 60-66].”
Alkali-activated binders: A review: Part 1. Historical background, terminology, reaction mechanisms and hydration products (2008, background): “As for Song et al. [ 65 ] the main reaction product of blast furnace slag hydration is CSH gel with minor amounts of hydrotalcite, that was detected by XRD analysis, which are formed only when the slag achieves a high level of hydration [66].”
Properties of Two Model Soils Stabilized with Different Blends and Contents of GGBS, MgO, Lime, and PC (2014, background): “GGBS used on its own shows a slow hydration rate, resulting in a quite low early strength, and hence the GGBS hydration is usually accelerated by way of chemical activation (Wang and Scrivener 1995; Song et al. 2000; Shi et al. 2006).”
Isothermal reaction kinetics and temperature dependence of alkali activation of slag, fly ash and their blends (2013, background): “Activation of slag by alkalis is dependent on the efficiency of the alkalis in solubilizing the silica and alumina from slag [23,38].”
Strength and hydration properties of reactive MgO-activated ground granulated blastfurnace slag paste (2015, background): “Song et al. [4] claimed that the pH should be over 11.5 to initiate the activation process, while in another study, the value is reported as 12 [58].”
